WebJan 1, 2024 · The SEM images of the Cu-Mo-Ag, Fig. 3 (a–c), display hillock formation only for the 600 and 800 °C films. The 400 °C film surface was flat and smooth save a few sample preparation scratches. Both the 600 and 800 °C films contained a high density of hillocks evenly distributed throughout the surface with similar hillock morphology as Cu-Ta. WebDec 15, 1995 · The addition of Cu to pure Al significantly decreased the hillock density, but the addition of W to AlCu films increased the hillock density. Indeed, no hillocks were observed in AlCu films. However, there was an abundance ofAIzCu pre- cipitates on the annealed AlCu wafers. For this reason, the hillock densities of AlCu films are not … WebFor a fixed treatment time of 30 s, the density of Cu hillocks in the H2-treated sample (Figure 8(a)) is much lower than that in the NH3-treated sample (Figure 8(b)), suggesting that the reactant gas also contributes to the formation of Cu hillocks.
